This has to do with the non-free nature of the images. The communities have decided they did not want non-free images to be used more than the bare minimum possible, so a non free image like a movie poster is not returned as a page image.

Hello,

I am writing with a question regarding the OpenSearch API, which is super useful for extracting summary information about a page.

For a lot of pages, the return items contain:
- text
- url
- description
- image

e.g. https://en.wikipedia.org/w/api.php?action=opensearch&search=Angela%20Merkel&limit=10&format=xmlfm&suggest=false&profile=strict

However, there are quite a few cases where the image property is missing, although the page features an image in the infobox. Example: https://en.wikipedia.org/w/api.php?action=opensearch&search=Solaris_(2002_film)&limit=10&format=xmlfm&suggest=false&profile=strict

In cases where the opensearch extension doesn't return an image, is there another API which allows extracting the infobox image if one is present?

Many thanks in advance for the help,
Gheorghe
